Where to backcountry

Hi peeps, a few of us are looking for a backcountry holiday where we can rent snowmobiles and roam free for a week or two. I cant seem to find anything definitive on stuff like that so is it something you have to tailor make yourself I.e.find a Hut to rent then find a snowmobile rent company?( Ideally looking for something in alaska)Any help would be greatly appreciated
